Too bad you had only two days to spend on this one!
The idea has solid bases and it doesn't lack of originaly, very uniqe.
Anyway I couldn't have more than 3 or 4 attempts, since the graphics is too static and miminal for me, and in the end it was a little bit stressful finding one of the right numbers.
Maybe the rng is a little too much, sometimes I had a streak of "14" for like 6-7 times in a row, and sometimes I could find just one of the three numbers on an island that was appearing when it was too late (had to stop on the "game over" screen and confirm that there weren't other numbers I didn't catch while playing). Maybe just my bad luck :P

Yes, I had planned some more tweaks for the game, though I couldn't squeeze our more hours this time. It's a really simple algorithm - one random port of each island is connected to another random island to ensure there is a connection, the other ports are purely random. I had something a tad smarter in mind to ensure you can reach more or less any island with a few hops or so, but I couldn't come up with a solution right away and postponed it.
So indeed you can become stuck on a path that eventually leads to nowhere. Sorry. :) It shouldn't happen that often however.
